First record of the nesting whitefly, Paraleyrodes minei Iaccarino, 1990 (Hemiptera, Aleyrodidae) in Malta [PDF]

open access: yes, 2016
The nesting whitefly, Paraleyrodes minei is the latest exotic whitefly species to be found breeding in Malta and was originally described from specimens collected from Citrus crops in Syria by Iaccario (1990).

Dismantling the genus Tarenna (Rubiaceae: Pavetteae) in Africa and Madagascar, with the description of three new genera

open access: yesTAXON, EarlyView.
Abstract As presently circumscribed, the Paleotropical genus Tarenna, belonging to the tribe Pavetteae (Rubiaceae), comprises about 200 species and has its centres of diversity in tropical Asia and Africa. Previous molecular phylogenetic studies of the tribe revealed the polyphyly of Tarenna, suggesting that the genus needs to be recircumscribed ...

Contributions of historical and contemporary geographic and environmental factors to phylogeographic structure in a Tertiary relict species, Emmenopterys henryi (Rubiaceae)

open access: yesScientific Reports, 2016
Examining how historical and contemporary geographic and environmental factors contribute to genetic divergence at different evolutionary scales is a central yet largely unexplored question in ecology and evolution.

The Rubiaceae of Cabinda (Angola) [PDF]

open access: yesBotanical Journal of the Linnean Society, 2007
A treatment of the Rubiaceae of Cabinda (Angola) is presented based on various herbarium collections. There are 67 genera and 169 species of Rubiaceae represented in the flora of Cabinda. Eight entities are unnamed and could represent new taxa. Identification keys are provided for species and infraspecific taxa.

Phylogenomic study of Burkholderia glathei-like organisms, proposal of 13 novel Burkholderia species and emended descriptions of Burkholderia sordidicola, Burkholderia zhejiangensis, and Burkholderia grimmiae [PDF]

open access: yes, 2016
Partial gyrB gene sequence analysis of 17 isolates from human and environmental sources revealed 13 clusters of strains and identified them as Burkholderia glathei Glade (BGC) bacteria.

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

Phylogeny Predicts the Quantity of Antimalarial Alkaloids within the Iconic Yellow Cinchona Bark (Rubiaceae: Cinchona calisaya)

open access: yesFrontiers in Plant Science, 2017
Considerable inter- and intraspecific variation with respect to the quantity and composition of plant natural products exists. The processes that drive this variation remain largely unknown.

To converge or diverge? Phenological shifts driven by plant genome size and functional traits under nitrogen deposition and mowing

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Linkages between genome size (GS) and phenology underscore the diversification of functional traits, which are indicative of life‐history and resource acquisition strategies.

Isoptopic evidence of the transfer of nitrogen fixed by legumes to coffee trees [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2000
The use of isotopic methods has made it possible to quantify the contribution of nitrogen fixed by a coffee plantation. Thanks to the use of the natural 15N abundance assessment technique, we were able to show that, in field condition, roughly 30/ of the
